UNITED STATES PATENT O FICE,

PAUL RICHTER, OF NEW YORK, N. Y.

SIZING A ND FILLING FOR COTTON CLOTH AND OTHER FABRICS.

SPECIFICATION forming part of Letters Patent No. 278,183, dated May 22, 1883.

' Application filed December 22,1882. (No specimens.)

To all whom it mag concern:

Be it known that I, PAUL RICHTER, of the city, county, and State of New York, have invented a new and useful Improvement in a Sizing and Filling for Cotton 010th and other Fabrics, or any material requiring a firm though soft and pliable filling, also a sized and filled cloth, and the process for manufacturing the same; and I hereby declare thelfollowing to be a full and clear description thereof.

The object of this invention is to produce a filling for cotton cloth and any other goods, so as to make the goods treated with theimproved sizing and filling present a smooth, hard surface capable of being painted or printed upon,

and at the same time improve the quality and durability of the goods over those manufactured with the present forms of filling, which consist, chiefly,ot' clay in one form or another, chalk, whiting, &c. This improx'ed filling makes the-goods at once dense and pliable, so that they will lie flat or can be rolled without injury.

The invention consists of adding to the size or glue a quantity of paper-pulp finely ground or macerated, so that it, with the sizing, may enter into all of the pores and meshes of the goods or articles treated. The glue or sizing used for this purpose may be any of those now in use, or suitable for the purpose, and the paper-pulp may be of any particular quality suited to the special goods under treatment;

Thus for very fine work linen-paper pulp should be used, while for coarser work coinmoner qualities of paper-pulp may be used,

'After applying the size to the goods, the goods so treated should be passed through a pair of ,calendering-rollers, which willleave the surface smooth and hard and in a perfect condition to be printed or painted on.

The goods sized with my improved sizing and filling can be printed upon or painted on without any further sizing or filling, and without any stretching or other manipulation, thereby greatly cheapening the cost of manufacturing certain lines of goods, such as window-curtains and similar goods.

The goods produced in the manner above described constituteanew article of manufacture, being strong, soft, perfectly filled, and durable, unlike goods filled with clay, starch, &c., which are harsh and brittle, the new article of goods meeting a want in the trades that the inferior goods could never fill. These goods can be used for show-cards, book-covers or book-cloth, window'shades, and various other eminently adapted to wrappings for packages,

such as is required for goods making sea voyages.

Having described my invention, I claim- 1. The improved sizing and filling for cotton cloth and other fabrics, consisting of a size of glue or other similar sizing mixed with finely ground or inacerated paper-pulp.

2. 'The process of manufacturing a new article of sized cloth by coating the same with a sizing mixed with paper-pulp, and then passing it between calendering-rollers.

3. As a new article of manufacture, a cotton cloth or other fabric coated with a mixture of sizing and paper-pulp, and hardened by pressin g the same between calendering-rollers.
